Description

Technical Field

[0001] The present invention relates to the field of navigation technology, and in particular to a Doppler very high frequency omnidirectional beacon health monitoring system, method, equipment and medium. Background Art

[0002] Doppler VHF Omnidirectional Range (DVOR) is a short-range navigation device specified by ICAO. It provides the magnetic position of aircraft relative to the ground VHF omnidirectional range beacon station and is an important guarantee for civil aviation flight safety. In recent years, with the development of the civil aviation industry, the number of civil aviation flights has continued to grow. The reliable and stable operation of DVOR can ensure civil aviation safety.

[0003] For a long time, my country's DVOR equipment has been mainly imported. In the daily operation and maintenance of DVOR, there are few relevant literatures at home and abroad on how to deeply analyze the causes of failures and take corresponding countermeasures to better serve the actual operation of equipment. For a long time, my country's DVOR equipment has been mainly imported, and there is a lack of an effective real-time health monitoring method for DVOR equipment.

[0004] In recent years, domestically produced DVOR equipment has begun to be equipped in civil aviation navigation stations. This can give full play to the advantages of localization, establish a DVOR equipment health monitoring system, monitor the operating status and health status of DVOR equipment in real time, conduct inspections and maintenance in a timely and effective manner, ensure the continuous and reliable operation of domestically produced DVOR equipment, shorten the maintenance cycle of DVOR equipment, and better ensure civil aviation safety.

[0005] The "China Civil Aviation Next Generation Aviation Broadband Communication Technology Roadmap" released by the Civil Aviation Administration of China clearly states that "according to the application needs of the civil aviation industry and the relevant requirements of aviation safety communications, the construction and application of civil aviation 5G private networks / public networks will be carried out, covering airports, air traffic control, airlines, passengers, supervision and other operational scenarios". In recent years, civil aviation industry units such as China Southern Airlines Group, Daxing Airport, Xiamen Air Traffic Control Station, and CASC have begun to use operators' 5G virtual private networks for civil aviation production. Air traffic control and navigation stations are distributed over a wide area. Currently, they mainly rely on leasing operators' wired private network lines to access the civil aviation private network. The cost of building a physical dedicated 5G private network is high. Mobile operators can provide civil aviation with a wide-area access, secure and reliable 5G exclusive virtual private network, which can be used for wireless transmission private networks for air traffic control core services (communication, navigation and surveillance).

[0006] Disadvantages of the existing technology:

[0007] 1. DVOR equipment users can only monitor whether the equipment has alarm information, but cannot further analyze or predict the health status of the DVOR equipment based on the monitoring data.

[0008] 2. The on-site maintenance personnel or technical support personnel of the DVOR equipment can only report and communicate abnormal conditions of the on-site DVOR equipment through conventional communication methods such as WeChat, DingTalk, and telephone, and information communication is not timely and accurate.

[0009] 3. DVOR has 48, 50 or 52 sideband antennas. The health of the sideband antennas is mainly checked by climbing onto the ground grid during quarterly and annual maintenance, manually checking the firmness of the antennas one by one, and measuring the indicators of the sideband antenna cables one by one.

[0010] 4. The health of the DVOR sideband amplifier can only be indirectly judged by the changes in the 9960Hz modulation index, and the health of the sideband amplifier cannot be directly analyzed. Summary of the invention

[0049] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with embodiments and drawings. The exemplary embodiments of the present invention and their description are only used to explain the present invention and are not intended to limit the present invention.

[0050] Example 1

[0051] like Figure 1As shown, a Doppler VHF omnidirectional beacon health monitoring system provided by an embodiment of the present invention includes a health monitoring server and a DVOR operation and maintenance mobile terminal. The health monitoring server and the DVOR operation and maintenance mobile terminal communicate with each other through a 5G virtual private network. The DVOR health monitoring system receives the monitoring data of multiple DVORs from the intranet of each navigation station, and is isolated from the intranet of the navigation station by a firewall. It can only receive the monitoring data of the DVOR equipment in one direction and cannot control the DVOR equipment. The system is scalable and can monitor multiple sets of DVOR equipment at the same time. The health monitoring server is the background processor of the health monitoring software.

[0052] like Figure 2 As shown, the health monitoring server includes: a whole machine health monitoring module, a working parameter monitoring module, a module-level monitoring module, a sideband antenna monitoring module, a sideband amplifier monitoring module and a data storage module; the whole machine health monitoring module is used to monitor the overall status of the Doppler VHF omnidirectional beacon device; the working parameter monitoring module is used to periodically monitor the monitoring parameters and parameter alarm status of each monitor; the module-level monitoring module is used to monitor the health status of each extension or module; the sideband antenna monitoring module is used to monitor the reverse detection value and the standing wave ratio value of each sideband antenna in real time, and dynamically display the changes in the reverse detection and standing wave ratio detection values ​​of each sideband antenna in the form of a dynamic curve, and calculate the health status of the sideband antenna according to the reverse detection value and the standing wave ratio value; the sideband amplifier monitoring module is used to obtain the actual monitoring data of the amplitude and phase of the four sidebands, and calculate the health status of the sideband amplifier based on the comprehensive analysis of the actual monitoring data of the amplitude and phase of the four sidebands; the data storage module is used to store the monitoring data and health status of the Doppler VHF omnidirectional beacon device. The data storage module saves the historical monitoring data of the equipment. Users can view the working status, working parameter information and health status of all monitoring devices in a hierarchical manner through the terminal.

[0053] The user can view the overall status of the monitored DVOR device through the whole machine health monitoring module, which includes offline, standby, warning, and alarm. The user can view the detailed monitoring information of the DVOR device according to the device icon on the main interface of the software, which includes working parameter monitoring, module-level health monitoring, sideband antenna monitoring, and sideband amplifier monitoring information.

[0054] like Figure 3 As shown, the working parameter monitoring module uses 1s as a cycle to periodically monitor and display the monitoring parameters and parameter alarm status of monitor No. 1 and monitor No. 2. The monitoring parameters include azimuth, 30Hz modulation depth, 9960Hz modulation depth, carrier power, identification code, 1020Hz modulation depth, 9960Hz frequency modulation index, carrier frequency, carrier amplifier temperature, etc.

[0055] The health monitoring server also includes an equipment alarm module, which is used to send out alarm signals and prompt signals in the form of sound, light and electricity when the equipment shows abnormal health status. When the sideband amplifier fails, it locates the fault point and gives maintenance and troubleshooting suggestions.

[0056] When an alarm occurs in a parameter, the alarm status is indicated by color. When the parameter is in warning, the alarm status color is yellow, and when the parameter is in alarm, the alarm status color is red. The alarm parameters, alarm values ​​and other information are simultaneously announced in the form of voice broadcast.

[0057] like Figure 4 As shown, the module-level monitoring module is used to monitor the health status of 7 extension modules, including antenna, transmitter No. 1, transmitter No. 2, monitor No. 1, monitor No. 2, power supply No. 1, and power supply No. 2. Gray, green, yellow, and red are used to indicate the health status of standby, normal, warning, and alarm. The health status of the transmitter is the comprehensive result of the health status of the signal excitation submodule, upper sideband amplifier module, lower sideband amplifier module, and carrier amplifier module;

[0058] The health of the power supply is a comprehensive result of the health of the 50V output, 12V output, 6V output, and 5V output.

[0059] The DVOR host device integrates the reverse detection and standing wave detection functions of the sideband antenna, and reports the reverse detection value and standing wave ratio value to the sideband antenna monitoring module at a period of 1s. The sideband antenna monitoring module monitors the reverse detection value and standing wave ratio value of each sideband antenna in real time, and dynamically displays the changes in the reverse detection and standing wave ratio detection values ​​of each sideband antenna in the form of a dynamic curve. If the reverse detection value and standing wave ratio value have a tendency to deteriorate, or have a tendency to jitter abnormally, an alarm will be given. The sideband antenna monitoring module calculates the health status of the sideband antenna based on the received reverse detection value and standing wave ratio, and indicates the status of each sideband antenna in the health display interface with green, yellow, red and other colors, such as Figure 5 shown.

[0060] like Figure 6 , 7As shown, the sideband amplifier monitoring module is used to obtain the actual monitoring data of the amplitude and phase of the four sidebands, and calculate the health status of the sideband amplifier based on the comprehensive analysis of the actual monitoring data of the amplitude and phase of the four sidebands. If the sideband phase is abnormal and / or the amplitude is abnormal, the equipment alarm module will issue a sound and text alarm prompt, locate the fault point of the sideband amplifier, and automatically give repair and troubleshooting suggestions. By setting up the equipment alarm module, when the DVOR equipment has abnormalities such as early warning, alarm, and self-test faults, the alarm information can be automatically pushed to the DVOR operation and maintenance terminal of the technical support engineer in a timely manner, breaking through time and geographical restrictions to let engineers know the fault information of the equipment in a timely manner, which is convenient for timely processing. In addition, the fault point of the sideband amplifier can be located and repair and troubleshooting suggestions can be automatically given, which can save engineers' maintenance time and improve maintenance efficiency.

[0061] The health monitoring server also includes a health data recording module, which is used to record DVOR health monitoring data and data on device abnormalities uploaded during user maintenance or inspection.

[0062] Technical support engineers can view equipment monitoring data in real time through the DVOR operation and maintenance APP. The DVOR operation and maintenance APP is adaptable to mobile smart terminals of Android, Apple, and Hongmeng systems, and periodically receives the status, working parameters, monitoring videos, etc. of DVOR equipment from the DVOR health monitoring system in a 1s cycle.

[0063] When the DVOR's azimuth, 30Hz modulation depth, 9960Hz modulation depth, transmission power and other key monitoring parameters show jitter, exceed the threshold and other abnormalities, the APP will promptly remind the DVOR equipment user's technical support personnel through sound or vibration, breaking through time and geographical restrictions to achieve 7*24 hours of real-time online monitoring of VOR equipment. Users can upload photos, videos, or recordings of equipment abnormality alarms during maintenance or inspection to the health monitoring server through the joint inspection APP. Figure 8 , 9 Technical support engineers can upload photos, videos, or recordings of equipment abnormalities during maintenance or inspections through the operation and maintenance mobile terminal, and the operation and maintenance mobile terminal records and uploads the working parameters of the DVOR equipment inspection.

[0064] The embodiment of the present invention provides a Doppler very high frequency omnidirectional beacon health monitoring system, which can monitor the health status of the whole machine, extension or unit, working parameters, sideband antenna health, sideband amplifier health and other health conditions of DVOR equipment. When the DVOR equipment has abnormalities such as early warning, alarm, self-test failure, etc., the health monitoring system can automatically push alarm prompt information to the DVOR operation and maintenance terminal of the user's relevant technical support engineer in time. When the sideband amplifier is abnormal, the health monitoring system can locate the fault point of the sideband amplifier and automatically give repair and troubleshooting suggestions. It can also receive and save the data of equipment abnormal conditions uploaded by the technical support engineer through the DVOR operation and maintenance APP during maintenance or inspection and the working parameters of the daily inspection.
